The blade dispensing package of the invention, including the several forms of clinching means shown, is designed especially for use with a relatively small number of blades and although the line v.10. Fig. 11 is a perspective view of a blade package Fig. 10 with the; having been partly.

not limited to any specific number, is especially suitable for containing and dispensing a pack of four or five blades. The various structural details, together with the features and advantages hereinafter set forth, should be read with reference .to a four or five blade pack, bearing in mind the low cost requirements connected with such relatively small l The principal parts of the blade dispensing package of the invention include ,a blade carrier strip or wrapper-which is folded upon itself to form an inclosure and a clinching member for gripping the folded end of the wrapper to constitute a razor blade sheath in which a small number of blades maybe slidably received The fold-line along which the material is bent,

although not necessarily fixed at any given. point, is in general chosen in such away as to-result in forming an inclosure and sheath .portion of a depth lessthanthe length of' the blades .to allow exposed ends of therblades toproject outwardly in a convenient positionfor removal by the user. It is inherent inthe design of the package that'a clinching member of some resilience' be employed and the use of fthe term clinching means or member in -thesp'ecification is understood to refer to a "resilient type of fastening or gripping means which in all cases is. adapted to engage externally the twoopposite sides of aj'bladd wrapper,fthus' to Amman and constantlymaintaindight compres sive forces which firmly hold the blades and adjacent wrapper portions against one another.

For example, in one simple form of the invention as shown in Figs. 1-3 inclusive, in which the clinching member operates from the external surfaces only of the wrapper, numeral 2|! refers to a flexible wrapper which may be of any suitable material such paper, plastic, or similar substance occurring in sheet'form. One end 22 of the strip is folded over upon itself as indicated in Fig. 1, to provide a blade sheath in,w.hich are slidably received a plurality of razor blades 24, arranged in longitudinally and progressively,overlapping relation. The folded end 221s compressed against the blades as shown,

by means of a clinching member 26 of the type commonly, referred to as a paper clip, having wire ends or legs which are spread apart and slidably engaged over the opposite sides of the folded wrapper extremity 22. In the particular form, of clip noted, there .are two spaced ends of the clip bearing against one side of the wrapper andeanotherend bearing against the opposite side of the wrapper. at a point between the said first two clip .ends. As the clips seek to assume theirnornral position,- they exert compressive forces on two sides of theblade package for compressing the blades and immediately adjacent strip-portions against one another, thus producingan-appreciable frictional engagement, bymeans of which; the blades are held in fixed relation in the sheath. The length of the sheath is chosen so as to leave exposed ends of the blades proiectingoutwardly in a convenient position for withdrawal. I It will be observed that application of a compressive force occurs against one side of the wrapper at a point substantially midway thereof, while two other compressive forces are exerted on the other side of the wrapper at points more nearly adjacent the outer edges and as a result of this arrangementthere is induced a flexing of the blades and adjacent carrier strip portionsin such a manner that they are bent or,-bowed transversely of themselves. Advantage. is taken ofthe fact that the median slots of theblades facilitate be ding along a longitudinal axis.- 1The bowed cifect is more clearly disclcsed'inFig. 2. ,The principal advantage derived from the bowed shape. of the blades is increased frictional engageme t of each'blade with respect to an adjacent blade and increased stiff- -ness-of the individual blades, thusimparting greater stability and rigidity to the pack as well *as: ,decreasingthe possibility of accidental dis- .placementof ,a blade: Such a combination of a" limited number ofblades and single carrier strip folded upon itself comprises a simple, cheap andieasily assembled unit, convenient to handle andwell adapted to forming a, sales package for dispensing a limited number of razor blades. If

desired, an. outer, covering may be applied to Jsealthel blades against moisture.

:The blade packageillustrated in Figs. 5 and the package above described includinghowever a oused blade compartment formedby attaching. at the under side *ofthe wrapper anexteriorwall 30., which may besecured, for 'exampla by adhesive applied along its edges. It may also be desired to. form the wall 30 integrally with the wrapper so. that there provided at least one connecting edge by which the wall portionm'a'y be folded -overon adjacent portions of-the wrapper. ns-may: be seen inFig. 5,-the partition-'elementill is formed 38 in the manner customary with a fastening of the staple type in which ends of the staple pass through the wrapper and are bent overto resiliently grip the intervening wrapper portions. Blades 40 are received and held in the sheath portion by'the compressive forces exerted. Fig. 4 also illustrates a stacked arrangement o'fthe blades, one directly above another, which may be resorted to in place lapping arrangement elusive. g a V In Figs. 7-9 inclusive, there has been illustratof the longitudinally overdisclosed in Figs. l-3-'in ed the combination of a blade wrapperwith a:

clinched member which not only applies compressive forces at two outer sides of the wrapper, but also passes through both the wrapper and the blades to constitute a novel guide rib means. Blades 44 arranged in longitudinally overlapping relation, are slidably received in the manner already described, in a sheath formed by folding a wrapper 46 upon itself to present a folded end 48 of a length less than the length of any one of the blades 44-. Aclinched member 50 of resilient character is slidably engaged against the folded portions of the wrapper in the same general way common to-the clinched members already noted. Along that portion of the clinched member 50 which'occurs adjacent to the under side of the wrapper 46 are formed guide rib portions 52 and 54, which may conveniently be constructed by cutting out portions of the clinched member and bending them over into a right-angularly extending position so that they lie in spaced-apart relation and in parallel alinement; The under side of the wrapper is cut away to leave slots through which the guide ribs 52 and 54 are allowedto pass.

The upper side of the clinched me'mber50 may also be cut away to define a slot 56 which is in register with the guide ribs 52 and 54, and the portion of the wrapper occurring between the top of the clinched member 50 and the uppermost blade 44 is also recessed to define a slot through which the guideribs may extend. The guide rib arrangement :describedfunctions to maintain all of the blades in parallel alinement with one another, and moreover the rib tends to check displacement of the blade in a longitudinal direction to a limited degree. It will be observed that in removing a blade from the blade pack it must be passed over the rib without too great interference and this operation is provided for by forming the top edges of the rib portions with a bevel which gradually meets the plane in which the lowermost blade is located. If desired, the inner lowermost'end of the beveled edge may be slightly rounded. When a blade is-pulled away from the sheath, its central portion immediately adjacent to the end of the slot is caused to slide upwardly and over the rounded end and then along the beveled edge so that a releasing effect is achieved. In using a clinched member with the inte al b structure. described. it. may also be "desirable; to secure the. under side ,of/ the clinched member with tabs. :60. .Itzmay-ua o befoundv desirable to provide:..the. hody;--p,ortion of the wrapper with 62- which is located. to. allowhe. Wrapper-t0 e bent :or flexed awayfromv the groupcofbla thus leaving them in az-somewhatmol'c accessible position :forv handling.,;'l.he cover. is

formed with an opening 66 to :registerwiththe rib whenina closed. positiom .An: alternate method of; construc in a uid isto form a clinched member with aniexternal or separately applied projection in. the mann r suggested. in Figs. 10-13 inclusive.

.Ilfifi therein, a. wrapper; 10; .is :folded: up n. it elf o present an overlapping end;1 2 .WhiQh.--*fQ f I a blade sheath portion. Theiendj L2 is secured as before by a clinched member 14 which frictionally-secures-the blades 16., Ribs 18 :fcrme in the member 14 ,(Fig. '13-). extendunwardly, projecting. through the opening 80 ,in the :upper wall ofithe clinched member 14. The rib passes through a slot 82 in the; wrapper {Bias may. ,be more clearly seeniinFig. 13., Gombined-with'the back of the wrapper is -a wall :or panel "84which may be separately secured to the wrapper in any desired manner as by adhesivaand which overlies the under sidetof the clinched member. As aresult of this arrangement,,,it.- that :the clinched member serves .theadditional function of providinga smooth, hardabearing surface along which the end of a blade may be passed as the blade is inserted in the compartment formed by itself and. the partition 84. Since the clinched member 'is preferably formed of :a material such as metal-or other relatively hard substance, a durable surface is presented alongwhic'h a number of blades may be easily slid without danger of cutting.

.The rib construction may be utilized at other points than at the under side of the clinched member as has been indicatedin Figs. 14 and 15 general character described. The folded end 92 a razor blade slot. be more clearly seen rib in various other is in'this case provided with a slot 98"through which'the rib may extendinto engagement with The rib 96' and wrapper-may in'Figs. l6 and 17.

I It may further be desired to utilize a locking ways as for example by forming a ribportion directly in the wrapper instead of in the clinched member, and such an arrangement has been suggested in Figs.'18, 19 and20,-in which a wrapper'element l 00 is formed with folded end I02, containing blades I04 which are clinched in place by a member I116. The wrapper is constructed with a rib or corrugated portion I08 projecting upwardly in position to register with the slots of blades. [04.
